Hi-Core® XL Natural Glazing and Construction
Panels
Hi-Core® XL Natural is a rigid, multi-wall, translucent
sheet, made from a tough polyolefin alloy that is protected
from UV and weather by an Environmental Protection System that
is exclusive to Matra Plast. Light passing through Hi-Core® XL Natural is highly diffused, (over 95%). Diffused light is bent to many
different angles. Compared to non-diffusing materials, Hi-Core® XL Natural allows the light to make a service building brighter or to
penetrate deeper into the leaf canopy to impact with more crop.
Hi-Core® XL Natural Installation Notes:
-
Sheets are ready to use. There is no masking film to remove
or landfill.
-
Both sides are UV protected. Either side can
face the sun.
-
Any type of silicone or caulking can be used.
-
Join panels with standard aluminum, or PVC joiners. Allow
for expansion and contraction with temperature changes.
-
All sheets
should be point fastened to purlins, to industry
standards for multi-wall glazing sheets. The holes for
point
fastening screws should be predrilled, 1/8” oversize,
to allow for thermal expansion to prevent unsightly bowing
of the installed
sheets. Fasteners should be tight but should
not crush the surface.
-
Easily cut to size or shape with a utility knife
after gable installation. Saws easily without chatter
using fine carbide finishing blades.
-
Aluminum foil tape on
the top
and vent tape at the bottom will prevent dust and
dirt accumulation in the flutes over time.

| Sheets can be cold bent on site in the length
of flute direction to these minimum radiuses: |
| Cold Bend Radius |
36" |
48" |
| Thermal Expansion: Temperature Range Coefficient
of Linear Thermal Expansion (mm/mm/° C x 10-5) |
-30° C to 0° C - 12 |
0° C to 30° C
- 14 |
30° C to 60° C

| As a general rule, allow 1/8" per foot (10mm
per m) of length or width for expansion at average temperatures. |
| Water vapour absorption: 24 hours - 0.03%,
6 months - 0.06% |
| Custom Shading |
Available tinting can reduce light transmission
to a range of levels down to as low as 0% on request. |
| UV Protection |
Both sides of these glazing panels are protected
(2-sides UV) by a proprietary system.
Actual installed life depends on geographical
location and details of the installed orientation.
Hi-Core® XL Natural is an excellent glazing choice for applications where both
sides of the sheet are often exposed to the sun. |
